I would just like to respond to this message with a simple fact. C# is NOT in ANY WAY Db. They sound the same maybe on a trombone or tuba or trumpet. but C# should be pointed and Db should be curved. Strings players have the andvantage of distinguishing between enharmonic tones. In Theory, these tones are totally different; one is C raised, the other is D lowered. I reality, they are the same, but we must venture outside of the real world in music. If you were to play in the key of Db, the notes would be Db, Eb, F, G, Ab, Bb, C, Db, NOT C#, Eb, F, G, Ab, Bb, C, C#. The reason for this is that there are 2 C's played in this scale (C, C3). They are different tones, but still named the same (A sharp doesn't neccisarily denote the tone from being a C). Thus, C# and Db are different notes. They may be the same tone, but different notes altogether. I can see me getting a lot of flak for this one, but ask your music teahcer or anyone who's studied theory for a while (like me), they will agree
